Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 5 trades carry the job here, and each is compared with its US median. The weighted result for St. George is 0.85 times the national level.
For carpenters (47-2031, weighted 45%) the local median is $22.63 an hour, which is 22% below the national $29.12. The middle half of them earn between $19.45 and $28.36 an hour. BLS counts 1,110 of them working in the area, 122.7 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
Construction laborers (47-2061), 20% of the weighting: a median of $21.96 an hour, 3% below the US median of $22.66. The middle half of them earn between $18.37 and $23.78 an hour. About 1,500 work in the metro. That is 165.7 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
For cement masons and concrete finishers (47-2051, weighted 15%) the local median is $23.11 an hour, which is 16% below the national $27.41. The middle half of them earn between $22.22 and $28.78 an hour. BLS counts 520 of them working in the area, 57.5 for every 10,000 jobs (US: 13.3), so the local bench is deeper than average.
Electricians (47-2111), 10% of the weighting: a median of $27.17 an hour, 11% below the US median of $30.38. The middle half of them earn between $22.22 and $35.91 an hour. About 490 work in the metro. That is 54.1 per 10,000 jobs, compared with 48.7 nationally, so the supply of crews looks typical.
For roofers (47-2181, weighted 10%) the local median is $23.86 an hour, which is 10% below the national $26.65. The middle half of them earn between $20.75 and $30.31 an hour. BLS counts 260 of them working in the area, 28.7 for every 10,000 jobs (US: 8.7), so the local bench is deeper than average.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($28.36 an hour) instead of the median, the labor line grows by about $1,900. At the 25th percentile ($19.45) it shrinks by about $1,050. The total moves by 4.8% or 2.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 90,500 jobs in the St. George area. That makes it the 219th largest of the 300 metros we cover, with 0.06% of US employment.

When to schedule detached garage in St. George
We use NOAA's 1991-2020 climate normals for St George (5 miles from the city center). These are 30-year monthly averages, not forecasts.
April through May and October are the stretches where pouring concrete runs into the fewest weather problems in St. George (3 of 12 months). January, February, March, November and December have an average overnight low of 40°F or below; June, July, August and September have an average daytime high of 90°F or more.
The 40°F line is a deliberately cautious stand-in. The American Concrete Institute's cold-weather guide (ACI 306R-16) defines cold-weather concreting around an average daily air temperature below 40°F, which is colder than our test of an average overnight low at or below 40°F, so we flag a few extra shoulder months. In cold weather crews may need heated enclosures, insulating blankets or accelerated mixes, and those measures can raise a quote.
Heat matters for concrete as well. With average highs of 90°F or more in June, July, August and September, crews often start early, wet the base and plan for faster set times.
St. George gets about 9 inches of precipitation in a normal year, including roughly 1 inches of snow. The wettest months are January, February and August (1.4 inches in February). Inside the workable window, April and May are the driest, at 0.7 and 0.3 inches. The station averages about 128 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.
